Unsurprisingly, those games have thrown up some ruddy excellent snaps - and seen some very funny moments captured on camera.

If you've already seen Ed Woodward's incredibly grumpy face, or Delph being taunted with a fake snake, then you have a (rough) idea of what's about to come.

If not, all the better. Without further ado, here are the best pictures of the round...

Derby County make Manchester United feel welcome at Pride Park

We're assuming "Rammie" is The Rams' mascot. Not the most inventive nickname on the planet, to be honest.

As a side note, imagine if Derby were to sign Loic Remy. The puns would be out of this world.

United fans mutiny in the stands

We think it's fair to say that Louis van Gaal's popularity rating was at an all-time low prior to the Derby match.

United went on to win 3-1, of course. This lot might have felt slightly sheepish at full time.

United's season is clearly taking it's toll on poor Ed.

Look into his eyes. Feel the pure, unbridled rage. Now run. Run for your life.

If there's not a kid waving a homemade tin pot about, it's not the FA Cup.

After incessant reverses for his side over the last couple of months, we haven't seen Louis crack a smile on the sidelines for a long, long time.

He almost managed it after the Derby victory. Almost.

Spurs fans enjoy their opener against Colchester

Though we all enjoy a "David versus Goliath" story in the cup, sometimes - just sometimes - it's fun to see the minnows get a bit of a battering.

That's exactly what Tottenham served up to Colchester in their clash at the Weston Homes Community Stadium. The Essex side had their dreams of cup glory brutally crushed and, as you can see above, Spurs fans loved every second of it.

Delph gets a warm welcome at Villa Park

Will Aston Villa fans ever forgive their ex-captain for abandoning them? No, no they will not.

Leandro Bacuna gets angry - you won't like Bacuna when he's angry

Manchester City's visit to Villa got pretty heated at times - and not just because of Delph.

Bacuna allowed his rage to get the better of him at this point. We do not condone such behaviour.

Your side are losing 4-0, the performance is abject and you're about to crash out of the cup. How do you respond?

By getting your belly out, of course!
